PATTERN MECHANISM FOR LOOMS, 80C.

SPECIFICATION forming part of Letters Patent No. 396,057, dated January 8, 1889.

Application filed June 11, 1888. serial No. 276,739. (No model.)

T 0 aZZ whom it may concern.-

Be it known that I, lVILLIAM \YATTIE, a citizen of the United States, residing at \Vorcester, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Pattern Mechanism for Looms, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to mechanism for operating pattern surfaces or chains in looms or other machines; and the object of my invention is to provide a positively-operated and comparatively simple organization of mechanical devices, by means of which certain bars in the pattern surface or chain may be repeated as desired without constructing successive similar bars. This result I accomplish by means of two pattern surfacesor chains, one main surface, which acts directly upon the loom or machine of which it is a part, and one auxiliary surface, the office of which is to keep up the motion in the parts while the main surface rests on the bars which it is desired to repeat. 011 the main patternsurface, in addition to the indicators required for the machine, is a series of indicators which act upon the auxiliary patternsurface mechanism in the same manner that the auxiliary surface acts on the main surface mechanism. Each of these pattern surfaces is moved in my improvement by an independent star-wheel driven each by its own pinwheel, and the pin-wheels are moved into or out of gear with their respective star-wheels, as indicated by the pattern-surfaces.

Referring to the drawings, Figure 1 is a side view of my improved movement. Fig. 2 is an end view, partly in section, on line X X, Fig. 1, looking in the direction of the arrow, same figure; and l igs. 3 and i are detail views.

111 Figs. 1 and 2, 1 represents the frame of the movement fastened by tap-bolts 2 to the loom or machine, of which it forms a part, at 3. The main pattern-surface is here represented as a common form of chain made up of links 4, which connect bars 5, upon which Fitted to turn freely upon the spool, clearing the ends of the pattern-bars 5, is a starwheel, 12, which is confined on the spool laterally by means of the small flange 13 integral with the spool, and the collar 14, fast upon the outer end of the spool; also, fast in frame 1 is a stud, 15, which has mounted loosely upon it a gear-wheel, 16, confined on the stud by a head, 17. Bolted to the face of the gear 16 is a flange, 18, which carries a sleeve, 19, on the outer end of which, free to slide lengthwise on the sleeve, but compelled to rotate in unison with it by means of the feather 20, is a-pin-wheel, 21, adapted to operate the star: wheel 12. The stud 15 and the sleeve 19 are made hollow to receive the rod 22, which is fitted to slide freely through the stud and sleeve. One end of the rod is screwed into the hub of the pin-wheel 21 and held in any given position by the check-nut 23.

Fast 011 the other end of the rod is a handhub, 24:, provided with a groove, 25, into which is fitted loosely'the yoke 26, which is engaged by the forked lever 27, pivoted at 28 on an arm, 29, cast on frame 1. On the top end of the lever 27, fitted to revolve loosely, is a roller, 30, which engages a cam, 31, mounted upon the hub ,32 of flange 37, which is fitted to turn loosely on a stud, 33, fast in frame 1. Cut in the cam 31 at suitable intervals, the determination of which is described farther on, are depressions 3a, a trifle larger in outline than the roller 30. Cast integral with arm 29 is a socket, 35, which 0011- tains a coil-spring, 36, which is retained in the socket 35 by a corresponding socket, 37, on the forked lever 27. The power of the spring 36 is sufficient to slide the pin-wheel 21 on the sleeve and force the roller 30 into a depression, 34:, when the cam 31 is turned into the proper position.

The flange 37 011 hub 32 has out upon its periphery a series of star-wheel points, 38,

occupying the same angular space as the depressions in the cam ill, and adapting it to be driven by a pin-wheel termed on. the end of the shat't 35), which is titted to slide 'trccly through a hollow stud, which holds the gear l in place on frame 1 in the same manner The pin-wheel (shown broken olt',) through which the indications of the patterirclmin are (0111111lllllCtllttl to the loom or machine. lt is 'l'requentlv desirable to turn the main pattcriechain by hand without disturbing the other parts. To acct'nnplish this, I l'orm in the loose star-wheel 12 a series of sockets, (18, located the same angular distance apart as the points ol? the freely in a hole in the hub ot goal.- ill, thus 1 acting the same as feather 2o, compelling the pin-wheel shaft 3!) to rotate in unison with the gear. The hub 42 is provided with a grt'iove, -t-l,into\\'hich is titted loosely a yoke, 45, similar to yoke ft; in hub 2i. Yoke is cngaget'l by forked lever lit, which, with hub 4-7 and artn 48, forms a bell-crank, which is mounted lotjisely on a stud,-l-ll, fast in an arnnfit), which projects lrom lramc l. (oiled on stud 44') is a spring, 51, one end of which is last to the head of the stud ll) and the other end of which is hooked into forked lever 4-6.

The spring is put in tension byturning the stud t9, and held by set-screw 52, and is of sutiioient force to slide pin-wheel shat't 23E) through its stud. ilhepcnding lrom stud 523 on arm t8 is an adjustable link, 54', the lower end of which is socketetfl on the end olf lever 55,1)iv0ted on stud 56, Fast: in frame Lever is provided near the joint with link 54, with a foot, 57, which is fitted to engage the projecting ends of the in('lieator-bars 5 on the pattern-chain on spool R, Figs. 1 and -.l-.

The projecting bar on the pattern-elmin, through foot 57, hits lever and with it, through link 54-, the arm of the bell-crank, drawing the pin 5%, Fig. 3, ol.' pin-wheel it out of line with its star-whcel 3% and allowingend of shaft ill! to rest in the dwell till oi' the star-wheel. The proper alignment ot pinwheel -l-l with its star-wheel,with reference to lllG lllOllUll imparted by passing a projecting nannder lever 55, is effected by adjusting the length of link 54- by means ol the socket. head (51 and threaded rod of the link \Vhen a short baris in position umlerthe foot 57, the spring 51 acts to throw the pin into line for engagement for star-wheel 39. Pinwheel 21 is slid into and out of line for engagement with star-wheel 1; in a similar manner by means ol? the cam 31 and spring at; through lever 27, and the alignment of pin and star wheel is el'lected by screwing the rod into or out of the hub of the inn-wheel 21.

The gear to is driven by the gear (12, fast on a shaft, ('33, which is a part of the loom or machine to which the :lrame .l is attached, and motion is connnunicated to gear 1t; through int'erlnmliate gear, U71, which runs loosely on a stud fast in the loom-frame 1; also, pivoted on stud 5t] are a series of levers, t35,which extend out over the pattern-chain and are provided with feet tit], each titted to engage a row of indicators on the patterlrehain. To the ends elf the levers are pivoted links 07,

through the fast collar l-t.

star-wheel, and in the collar it, last on the chain-spool, a socket, till, on the same circle with the centers ol sockets 8 in the starwheel. Free to slide in the socket (if) is a pin with a head, Ttl, at the inner end, which fills the socket, and provided with a spindle, Tl, which projects through a hole the size of the spindle in the shell at: the end ol the socket.

("onlined between the head of the spindle and the end of the socket is a spring, '72, coiled on the spindle, which is of snllicient l'orceto keep the pin in thesocket with which 11; i -ides in the star-whecl. \Vhcn in this posititm, motion is transmittml by the stat wheel from the Pill-Wheel to the chain-spool l astened to the ]llt)jt"(fl'lllg end of the spindle is a handle, '73, by which the pin may be withdrawn from the sockets in the stat-wheel, when the chain may be turned by hand, the star-whcel being held by the pin-wheel, the spool turn'il'ig within it. \Yhenever, For the nn-pose of picking out imperfect work or otherwise, it desirable to turn the main pz'itt'ern-chain by hand, as just described, it; will be necessary to turn the an .\iiliary cam 23] to correspond, or the main and auxiliary pattern-s11rt'aces would get out of time with each other. To acctnnplish this, I mount the cam 31 loosely on the hub 32, where it is confined by collar 74-. ()n the [hinge of the cam ill, I t'orm a spring-pin socket, 75, in which a pin, 70, works in conjunction with sockets T7 in the tlange 37 in the same man-- ncr as pin 7t) 72 in socket lit) with star-wheel l2. Sockets 7? are the sammlngnlar distance apart as the points of star-wheel 238. When the pin is .in the position shown in liig. the cam ill will be driven by star-wheel 38 and pin Tti may be withdrawn,allowing the cam to be turned indcpendently ot' the starwheel.

I use the projecting end of bars in the main pattern-chain toindicale t he movements olf pin-wheel -ll instead of the regular tubes and rolls, in order to save chain-stock. The work ol sliding the nn-wheel shaft is so slight that I experience no dilticulty in doing this. It will be further not iced by reference to liig. 2 that I use the same bar by reversin it, either for a projecting bar to act on foot 57, or for a short bar to clear foot 57, the projecting end when reversed passing the indicating-point idly. I thus avoid the contusion in building chain that would be incident to having two lengths olf bars, beside saving chain-st oek again.

The parts are so timed. that the pin-wheel on shaft 13f! has just tinished its action. on the stm whcel 538 when pin-wheel 21 comes into engagement with its star-wheel l2, and the time occupied by the action of both pin-wheels is something less than one complete revolution of the pin-wheels or of the shaft (53, the gears 16, 40, and (32 being all the same size.

The operation is as follows: The parts being in the position shown in the drawings, the pin-wheel 21 being in engagement and j nst beginning its action 011 the star-wheel 12, the action of pin-wheel 21 moves star-wheel 12 and with it the main pattern-chain, one angular space bringing a bar which it is desired to repeat under the levers and havin g a short bar in the row of indicators which act on lever 55. The short bar calls down link 54, which allows spring 51 to push pinwheel 141 through forked lever l6 into engagement with star-wheel 3S. Continuing the revolution, pin-wheel all moves, star-wheel 38 one angular space, which lifts roller 30 out of a depression in cam 31 and onto the face of the cam,which, through forked lever 27, slides rod 22 and moves pin-wheel 21 out of engagement with its star-wheel 12, leaving the dwell end of .the pin-wheel hub in line with the starwheel. Pin-wheel 21 being out of engagement, the succeeding revolution of the parts does not move the main chain-shaft, and the same bar is repeated. Pin-wheel 41 will continue to move its star-wheel one space each revolution, as long as no depression comes opposite roller 30 on cam 31; and the ends of the next presented bars do not project to hold the lever 55 in its elevated position, and the number of repeats desired determines the number of angular spaces on cam 31 which are to be left full face. When this number has been reached, a depression in cam 31 throws pinwheel 21 into engagement, and at the succeeding revolution the main chain is turned one space. The main chain can be kept in motion for as many succeeding revolutions as desired by putting projecting bars in the row of indicators which act on lever 55, thereby keeping pin-wheel t] out of engagement with its star-wheel. The main chain can be also kept in action by cutting depressions in the successive spaces on cam 31. The star-wheel 38 may be made with any convenient number of points, and the main pattern-bars repeated, according to the number of points in said star-wheel.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
